TO ALL WHOM ,IT MAY CONCERN: v

Be it known that I, FRANKIJIN NB'LSON, of Wyandotte,,county of :Waync, invented. a new and useful Improvement in Rail-Straightening Machines and I do hereby declare that the fol' lowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use thosan e, reference being had to the accompanying drawings, forming part of this spccilicatioh, in which-Q and State oi Michigamfhavd Figure 1 is a front view of the machine for straightening-rails of my invention. Fig iire'Z is a plan' ontop view of the-same. Figure .3 is' aside view of the same. I Thelobject of this invention is straightening rails or iron bars of a similar character, "when'hent, and itcon by a crank with akneefjhiut connection, in such a manner that-the greatest average power is applied when it is ni'ostneeded, the whole'arrangcment beingpxeeedingly' simple and powerfuL' "Similar letters of reference indicatelike parts. I

A A are standards of an upright cast-iron frame resting on a heavy base, B, on the inner side of which standards are grooves in which is fitted to slide up and down, a strong block or press-drop, 0, provided with an adjustable die, a. The drop G is suspended to a link, D,'the' upper forked end of which forms, a toggle or kneejoint connection with two links, one of which, 6, is pivoted at the upper end to'the top ofv the standards A A, and the other, a, is hung upon its outer end to a crank, d, as shown in'figs. 1 and 2." The crank d, which hangs in brackctsE E, on the standards A A, receives its motion from a spin-who cillating pendant or-link operated.

cl, F, which engages in a pinion, G,

on the driving-shaft e, actuated by th'e pulley H, and'carrying thefly-whecl I. On thebase B, are placed frames or-platforn'rs, K K, on each side of the standards A, which vibrate on the fralm'es are hung rollers, L L, which are balanced with weights,'M M, placed at the opposite sides of the frames,- K K. The rollers L L, are set so as to turn in line with the blocks N N, at the foot of the standards A A, which support the iron rail or bariwhich is who placed under the press-drop C, for straightening. It is manifest that if a rail is placed so as to rest on the supporting blocks NiN, and upon the rollers L L,'and the die is adjusted properly, that the motion of the crank 01 will cause the press-drop C to descend and bear upon the pivot-rods, g Upon the front sides of rail, so that any bend or crook in it aud-undefthe die a, will be forced down untilthe rail is made straight.-

The Hill is first rested on the rollers, but if the weightsare removed the rollers will dro that the rail shall rest only on the blocks N N, for straightening short bends. I

Hdving th'us'described my invention, what I claim as new, and desire to secure by Letters Patent, is

The sliding press-drop (3,"connected by atog gle joint with the crank-d, in combination with the vibrating roller frames K K, constructedand operating substantially as herein described. 4

The above specification of my invention signed by-ine this 6th day of October, 1866.
